I have a revolut account but I “would not” use them for trading ever.
I’d say its finance for the kids.
However I find it very useful for online purchases in foreign currency, meaning you can do this without your banks exchange rates.
Also very useful for buying foreign currency for holiday use. The revolut app let’s you hold many nationalities bank accounts and let’s you buy forex at near cost prices.
You can deposit and exchange a very small volume of cash commission free. You can use it as your debit card abroad as if it is a native card to the country you are on travelling in.
You can top it up with such small amounts of cash at the click of a few buttons, this means it is the card of choice for the lack of funds held within it until you need them means it is more secure if scammers are up to no good.
